Large data centers are complex systems that depend on several generations of hardware and software components, ranging from legacy mainframes rack-based appliances to modular blade servers modern rack scale design solutions. To cope with this heterogeneity, the center manager must coordinate a multitude tools, protocols, standards. Currently, managers, standardization bodies, hardware/software manufacturers joining efforts develop promote Redfish as main management standard for centers, even...
Traditional data center infrastructure suffers from a lack of standard and ubiquitous management solutions. Despite the achieved advances, existing tools interoperability are sometimes hardware dependent. Vendors already actively participating in specification design new software interfaces within different forums. Nevertheless, complexity variety components that includes servers, cooling, networking, power hardware, coupled with introduction defined paradigm, led to parallel development...
Summary Next‐generation cloud data centers are based on software‐defined center infrastructures that promote flexibility, automation, optimization, and scalability. The Redfish standard the Intel Rack Scale Design technology enable infrastructure disaggregate bare‐metal compute, storage, networking resources into virtual pools to dynamically compose create performance‐optimized (vPODs) tailored workload‐specific demands. This article proposes four chassis design configurations Distributed...
Summary To assess the availability of different data center configurations, understand main root causes failures and represent its low‐level details, such as subsystem's behavior their interconnections, we have proposed, in previous works, a set stochastic models to architectures (considering three subsystems: power, cooling, IT) based on TIA‐942 standard. In this paper, propose Data Center Availability (DCAV), web‐based software system allow operators evaluate infrastructure through...
The next-generation data center introduces the refactoring of traditional in order to create pools disaggregated resource units, such as processors, memory, storage, network, power, and cooling sources, named composable system (CSs) with purpose offering flexibility, automation, optimization, scalability. In this paper, we solve an optimization problem allocate CSs considering next- generation centers. main goal is maximize CS availability for application owner, having its minimum...
Summary A data center infrastructure is composed of heterogeneous resources divided into three main subsystems: IT (processor, memory, disk, network, etc.), power (generators, transformers, uninterruptible supplies, distribution units, among others), and cooling (water chillers, pipes, tower). This heterogeneity brings challenges for collecting gathering from several devices in the infrastructure. In addition, extracting relevant information another challenge managers. While seeking to...
With the continuous growth of number mobile devices connected to Internet, cellular network infrastructure owners are facing several new challenges. The fifth generation technology (5G) is planned enable a fully and society empower socio-economic transformations. In 5G, different scenarios with high strict requirements being deployed. To deal such heterogeneity, more advanced communication services required. Network Function Virtualization (NFV) combined distributed micro data centers (MDCs)...
